Advanced Video Display Processor 6
s Outline
YGV619 is a VDP (Video Display Processor) adopting OSD display control system which is best suited to the data broadcasting. The digital image interface of this device for connection with MPEG decoder has been improved. The use of this device allows screen composition that is suited to mobile information terminals, car navigation system, etc. Scan timing conforming to the display standard of digital TVs can be made. Two built-in PLL circuits allows to realize superimposition of external image signal on original image signal, and to produce clock best suited to SDRAM that is adopted as external video memory.
s Features
q Display planes: External digital image is overlaid with OSD images composed of regions.
Up to four planes, which are individually composed of back drop plane (plane on which external images are inputted) + region, are available.
q OSD image format:
8bit/dot palette mode, and 16 bit RGB or YCbCr format can be selected. YCbCr conforms to the conversion method of ITU601. Color palette (256 colors in 16777 k colors) can be specified by region.
q Digital image input format:
18bitR6G6B6 16bitYCbCr422 8bitITU656
(Max. dot clock frequency: 80 MHz) (Max. dot clock frequency: 80 MHz) (Dot clock frequency 27 MHz)
q Digital image output format:
R6G6B6 + 2 bit AT 18bitYCbCr444 + 2 bit AT 16bitYCbCr422 + 2 bit AT 8bitITU656 + 2 bit AT + 6 bit α blending coefficient
q Max. OSD resolution: 960 dots × 1080……
